YafaRay 0.1.2 Beta 4 has been released. We have fixed the arealight bug that produced wrong reflections and rendering of the light itself. Apart from that, normal mapping has been fixed and there is a first implementation of border rendering. However, border rendering is not finished yet, so just be sure you don't cancel rendering when border rendering is enabled or either Blender will crash. Please report your bugs and findings in this thread.

Since the arealight bug is a critical one, we recommend immediate upgrading.

Regards.

PD: to upgrade, you just need to be sure that the 'overwrite' tickbox is enabled in the files browser when you select the zip file of the new version

It was suggested that i post this issue here. I've been unsuccessful at getting a clean transparency from image files with an alpha channel or by using a BW image to affect the transparency channel. Here's the post for more info: http://www.yafaray.org/community/forum/ ... =22&t=4640

I've tried this in many different ways on several different computers and os's but no success. Is this a bug?

edit - I've submitted this into the bug tracker for review, there are more details there as well as a .blend file.

As far as i see, in the most renderings with Photon Mapping, the caustic photons are set to a minimum.Is this a reslut of a bug in the new versions or why did everybody use it in that way or miss i something in the last months and years?

AFAIK turning off caustics in many scenes is not due to a new bug. With some scenes (like an interior render with glass windows etc.) rendering with caustics can be very hard to manage, so it is easier then to just render without them.
